Thanks for linking to this! I've been building a toy language by mutating the excellent Lua 5.2 runtime, it's one of my silly side projects aimed at taking me out of my coding comfort zone. Looking into the LuaJIT code to figure out how they did it has been on my list for a few days now, and this introduction to DynASM provides an nice starting point (LuaJIT itself is based on Lua 5.1 and unlikely to be updated).
